AWS Controllers for Kubernetes

AWS Controllers for Kubernetes (ACK) lets you define and use AWS service resources directly from Kubernetes. With ACK, you can take advantage of AWS managed services for your Kubernetes applications without needing to define resources outside of the cluster or run services that provide supporting capabilities like databases or message queues within the cluster.

This is a new open source project built with ❤️ by AWS and available as a Developer Preview. We encourage you to try it out, provide feedback and contribute to development.

Important: Because this project is a preview, there may be significant and breaking changes introduced in the future. We encourage you to try and experiment with this project. Please do not adopt it for production use.


Kubernetes applications often require a number of supporting resources like databases, message queues, and object stores to operate. AWS provides a set of managed services that you can use to provide these resources for your applications, but provisioning and integrating them with Kubernetes was complex and time consuming. ACK lets you define and consume many AWS services and resources directly within a Kubernetes cluster. ACK gives you a unified, operationally seamless way to manage your application and its dependencies.

Connecting Kubernetes and AWS APIs

A bird's eye view of ACK

ACK is a collection of Kubernetes Custom Resource Definitions (CRDs) and controllers which work together to extend the Kubernetes API and create AWS resources on your cluster’s behalf.

ACK comprises a set of Kubernetes custom controllers. Each controller manages custom resources representing API resources of a single AWS service API. For example, the ACK service controller for AWS Simple Storage Service (S3) manages custom resources that represent AWS S3 buckets.

Instead of logging into the AWS console or using the aws CLI tool to interact with the AWS service API, Kubernetes users can install a controller for an AWS service and then create, update, read and delete AWS resources using the Kubernetes API.

This means they can use the Kubernetes API and configuration language to fully describe both their containerized applications, using Kubernetes resources like Deployment and Service, as well as any AWS service resources upon which those applications depend.

Getting started

Until we've graduated ACK service controllers we ask you to test-drive them.
